System and method for monitoring operation state of elevator car

ActiveCN102633173AIntelligent identification of failure to stop the elevatorIntelligent recognition of running performanceElevatorsCommunication unitControl engineering
The invention discloses a system and method for monitoring the operation state of an elevator car. The system comprises an elevator car operation state intelligent sensing unit, a signal acquiring and processing unit and a wireless communication unit. The method comprises the following steps of: sensing an accelerated speed of the elevator car and/or sensing a distance between the elevator car and a certain fixed reference system in a shaft; acquiring an accelerated speed signal of the elevator car and/or a distance signal between the elevator car and the certain fixed reference system in the shaft; carrying out state calculation and processing to obtain real-time operation state parameters of the elevator car; and carrying out intelligent monitoring algorithm and intelligent identification algorithm according to the real-time operation state parameters to obtain the real-time operation state of the elevator car. The system and method disclosed by the invention can judge the real-time operation direction (ascending, stopping and descending) of an elevator and judge whether the elevator operates at an over speed through intelligent monitoring, identification and estimation; the real-time flat bed floor number of the elevator car or the distance from the normal flat bed position of a certain floor layer can be obtained to intelligently identify the fault stopping of the elevator and an overhauling state; and the system and the method can evaluate the comfort level of the elevator, estimate the elevator risk, predicate faults and the like.

Externally reinforced concrete irrigated and heat preservation wall structure embedded energy-saving system and its construction method

The invention relates to an energy-saving system for a reinforced concrete outer-casting built-in heat insulation wall body structure and a construction method thereof, which can effectively solve the problems of external wall heat insulation of a high-rise building with high heat insulation requirement and cracking and falling of a heat insulation layer. The system is produced by a wall body and reinforcing steel bars in the wall body which are cast by concrete. The method comprises the following steps that: a reinforcing steel bar frame of the wall body is produced and arranged, namely parallel vertical reinforcing steel bars and indoor floor-connecting board tie bars perpendicular to the parallel vertical reinforcing steel bars are bound together, a grid board is hoisted and externally suspended outside the vertical reinforcing steel bars of the wall body, and is bound with the vertical reinforcing steel bars of the wall body by hooked bars and binding steel bars as well as framework positioning bearing bars, then a framework is arranged on the framework positioning bearing bars and is firmly bound with reinforcing steel bars of beams and boards of a floor, lapping bars are reserved, a heat insulation grid board is firstly arranged, then reinforcing steel bars of corbel brackets of a balcony and an air conditioning board external wall are bound, finally the concrete is cast, the curing is performed, and the framework is removed to repair the structure. The system has good heat insulation effect, energy conservation, environmental protection, simple method, and huge economic benefit and social benefit.
